Abstract
The present invention provides a kind of improvement soil matrix and its administering methods of Green Mine, by the cliff for modifying mine, form certain massif gradient, hard material is spread by certain way, then plastic coated metal net is covered, finally novel improvement soil matrix is covered with certain thickness, effective improvement in the mine Lai Shixian.The utility model has the advantages that improvement soil matrix can be stable float on the surface of the 80 ° of mines gradient <, cohesive strength > 20Kpa, 18 ° of internal friction angle >, index > 99.1% against corrosion, antiscour index > 2.0L.min/g, it is structural strong, washing away for heavy rain or more can be effectively resisted after sowing grass seeds by duster 3 days；It is abundant to improve soil matrix nutrition, it is loose, ventilative, it is suitble to the growth of plant；Due to using the organic matters such as a large amount of agricultural leftover bits and pieces, water resistance is strong, greatlys save construction cost and maintenance cost.
Description
Technical field
The present invention relates to the restoration of the ecosystem field in mine, and in particular to a kind of improvement soil matrix and its Green Mine are controlled
Reason method.
Background technique
In recent years, it due to the fast development of economic construction and to the excessive development and utilization of natural resources, produces a large amount of
Breakage mountain body, rock face and high abrupt slope are degrading the natural ecological environment on massif periphery, and there is the peaces such as landslide, collapsing
Full hidden danger；Since the nutrient and water supply of massif side slope is poor, vegetation faces the threat such as arid, sweltering heat, it is extremely difficult to restore；After excavation
Rock slope rock thickness, whole slopes height be steep, general soil matrix is difficult to anchor on rock, and hypothallus is thin, antiscour
Property it is poor, nutrient in the soil body is gradually lost as the time increases, and causes fertility to reduce year by year, massif side slope presentation water shortage lacks soil etc.
State, plant are difficult to survive, with ultraviolet radiation, wind erosion and water erosion, the consequence that slope surface may finally be caused to collapse.
At present generally excavated on mine by the way of alien earth sparging, using engineering mode planting trough method or
Bottom of slope transplants the method for vine to carry out mine reparation, these three ecological restoration of mine modes face high steep slope effect all
Undesirable, alien earth sparging matrix anchoring capability is poor, and hypothallus is thin, and shear resistance is weak, is especially easy in face of high steep slope by rain
The phenomenon that water washes away, and often duplicates construction, effect is very unsatisfactory；Plant life is such as excavated on mine using engineering mode
The method of slot, difficulty of construction is high, and construction cost is big；And by the way of vine, afforestation effect is too slow.
Summary of the invention
The purpose of the present invention overcomes the deficiencies of the prior art and provide a kind of improvement for improveing soil matrix and its Green Mine
Method.By modifying the cliff in mine, certain massif gradient is formed, hard material is spread by certain way, then covers plastic
Metal mesh is finally covered novel improvement soil matrix with certain thickness, effective improvement in the mine Lai Shixian.
The purpose of the present invention is what is reached by following technical measures: a kind of improvement soil matrix, by volume percentage
Amount, including amphiprotic polyacrylamide 0.1%~1%, plastic clay 33%~47%, powdered whiting 5%~10%, kaolin
5%~15%, hydrophilic agent 3%~8%, coagulant 0.5%~3%, organic matter 20%~34%, organic fertilizer 5%~10%, plant
Species 1%~3%.
Further, each component of the improvement soil matrix is uniformly mixed, is uniformly mixed with 20 DEG C~30 DEG C of water
Stirring.
Further, the improvement soil matrix and the volume ratio of water are 1:1~1:2,60~100r/min of mixing speed.
Further, the plasticity index > 17 of the plastic clay, wherein the sticking grain volume accounting > less than 0.005 ㎜
60%, 18 ° of cohesive strength > 20Kpa, internal friction angle >, pH5.5~8.5, plastic clay silt content < 25%.
Further, 800 mesh of powdered whiting mesh number >, wherein calcium powder content > 95%.
Further, the molecular weight > 5,000,000 of the amphoteric ion polyacrylamide, concentration 0.1%~0.5%, wherein
Acrylamide monomer content < 0.1%.
Further, the kaolin is powdered, and specification is 600~1200 mesh.
Further, the hydrophilic agent is that corrugated paper, polyethylene glycol oxide, polyvinyl alcohol, hydroxypropylation cellulose are therein
It is one or more of.
Further, the coagulant is one of inorganic coagulant, organic coagulants, high-molecular coagulant adopting or several
Kind.
Further, the coagulant is frerrous chloride, in magnesium carbonate, high molecular polymerization aluminium chloride, bodied ferric sulfate
It is one or several kinds of.
A kind of administering method of Green Mine, comprising the following steps:
1) 80 ° of gradient < for modifying mine, and remove danger stone, float stone and the rubble on surface；
2) plastic coated metal net and fixation are covered on the surface of mine, in the fixed cultivation body of rod in the inside of metal mesh；
3) the improvement soil matrix is covered on metal mesh with hydroseeder, improvement soil matrix cladding thickness is 7
~10cm.
Further, the cultivation body of rod is hard material.
Further, every square metre of the body of rod 2~4 rows of laying of the cultivation, two cultivation body of rod transverse lap length are 5~
10cm。
Organic matter is peanut shell, rice husk, wood powder, vinasse, straw, lignin etc..
Compared with prior art, the beneficial effects of the present invention are: improvement soil matrix can be stable float in gradient <
On the surface of 80 ° of mines, 18 °, index > 99.1% against corrosion, antiscour index > of cohesive strength > 20Kpa, internal friction angle >
2.0L.min/g, it is structural strong, washing away for heavy rain or more can be effectively resisted after sowing grass seeds by duster 3 days；It is abundant to improve soil matrix nutrition,
It is loose, ventilative, it is suitble to the growth of plant；Due to using the organic matters such as a large amount of agricultural leftover bits and pieces, water resistance is strong, greatlys save
